Description

위조방지 보호필름의 제조방법Manufacturing method of anti-counterfeiting protective film

본 발명은 위조방지용 보호필름의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a protective film for counterfeit.

여권이나 주민등록증 등 각종 신분증의 위조방지를 위하여 종래에는 흔히 철인을 사용한다던지 신분증에 점착픽름을 부착하는 수단 등이 사용되어 왔다. 그러나 철인을 사용하게 되면 사진이 손상될 염려가 있을 뿐아니라, 비교적 위조나 변조가 용이한 결점이 있으며, 열융착형 보호필름으로 피복한 신분증은 이를 가열하므로서 비교적 용이하게 피복층을 분리할 수 있어 사진의 교체가 가능한 결점이 있다. 그리고 사진위에 점착필름을 부착하는 수단 역시 점착필름을 가열시키므로서 신분증으로부터 점착 필름을 용이하게 박리시킬수 있는 결점이 있다.In order to prevent forgery of various IDs such as passports or resident registration cards, a means of attaching an adhesive film to an ID card or the like is often used. However, the use of iron man not only damages the picture, but also has the disadvantage of being relatively forged or easily tampered with. ID cards coated with a heat-sealing protective film can easily separate the coating layer by heating it. There is a defect that can be replaced. And the means for attaching the adhesive film on the photo also has a drawback that can easily peel off the adhesive film from the identification card by heating the adhesive film.

그리하여 보호필름 이면에 접착제를 도포하고 그 이면에 이형제를 도포한 후 인쇄잉크층을 형성시키므로서 이러한 보호필름을 사진위에 부착하였다가 떼어내면 보호필름의 이면에 인쇄되어 있던 인쇄 내용중 이형제가 개재되어 있는 부분이 사진위에 접착되므로 사진을 떼어낸 자리에 다른 사진을 부착하면 보호필름에 인쇄된 인쇄 내용중 이형제가 개재된 부분이 바뀐 사진 표면에 현출되지 아니하여 위조나 변조의 사실을 쉽게 인식할 수 있게하는 수단이 사용되기도 한다. 그런데 이와 같은 보호필름의 접착제층에 이형제를 도포하고 인쇄층을 형성시키는 일은 그 공정이 복잡하여 제조비용을 앙등시키는 원인이 되어 왔다.Thus, by applying an adhesive on the back side of the protective film, applying a release agent on the back side, and then forming a printing ink layer, the protective film is attached on the photograph and detached. Then, the release agent is interposed in the print content printed on the back side of the protective film. Since the part is glued on the picture, attaching another picture to the place where the picture is removed makes it easier to recognize the fact of forgery or forgery because the printed part printed on the protective film does not appear on the surface of the changed picture. Some means of doing so may be used. However, the application of the release agent to the adhesive layer of the protective film and the formation of the printed layer has been a cause of complicated manufacturing process to raise the manufacturing cost.

그리하여 본 발명은 보호필름의 이면에 인쇄된 인쇄층이 사진에 전사되게 하므로서 사진의 교체가 쉽게 판별되게 하며 교체되는 사진에의 인쇄 내용표현이 극히 곤란하게 하는 상기 수단에 있어서, 중합도 900-1500정도의 수용성 수지를 주재로 하고 이에 인쇄적성을 향상시키기 위해 알콜류 및 그리콜계 보조제를 혼합하여 인쇄용 바니쉬를 제조하고 이 바니쉬에 염료 또는 기능성 색소를 첨가하여 제조한 전사잉크를 보호필름 이면의 열융착형 접착제(EVA)층에 도포인쇄하여, 보호필름 이면의 접착제층에 이형제층을 형성시키지 아니하더라도 사진으로부터 보호필름을 떼어내면 보호필름의 접착제층에 인쇄된 인쇄잉크가 보호필름으로부터 떨어져 사진에 전사되도록 하므로서 이형제의 도포에 따른 기술적 곤란성을 극복하였다. 다만, 바니쉬를 제조하기 위한 수용성 수지는 아크릴 수지, PVA계 수지 띤 PVP계 수지 등이 사용될 수 있으며, 주재인 수용성 수지에 혼합하는 보조제는 수용성 아크릴 수지 40-70%량에 대하여 에틸알콜 20-40%, 에틸렌 그리콜 5-15%, 소포제 3-7%를 혼합하여 제조하는 것이 바람직하다. 이와 같은 본 발명을 실시예에 따라 설명하면 다음과 같다.Thus, the present invention allows the printing layer printed on the back surface of the protective film to be transferred to the picture so that the replacement of the picture can be easily distinguished, and in the above means for expressing the print content on the replaced picture extremely, the degree of polymerization is about 900-1500. It is mainly based on water-soluble resin, and in order to improve printability, a printing varnish is prepared by mixing alcohols and glycol-based auxiliaries, and the transfer ink manufactured by adding dye or functional dye to the varnish is heat-sealed on the back of the protective film Applying and printing on the adhesive (EVA) layer, even if the release layer is not formed on the adhesive layer on the back of the protective film, the protective ink is removed from the photo so that the printing ink printed on the adhesive layer of the protective film is transferred from the protective film to the photo. This overcomes the technical difficulties associated with the application of the release agent. However, the water-soluble resin for preparing varnish may be acrylic resin, PVA-based resin or PVP-based resin, and the auxiliary agent to be mixed with the water-soluble resin as the main agent is ethyl alcohol 20-40 with respect to 40-70% of the water-soluble acrylic resin. It is preferably prepared by mixing%, ethylene glycol 5-15%, and antifoaming agent 3-7%. When the present invention is described according to an embodiment as follows.

[실시 예][Example]

[제 1 공정][Step 1]

25% 아크릴산모노머 99부량에 중합개시제로 과황산 암모늄 1부량을 첨가하고 중합억제제로 트리페닐크로로메탄(Triphenyl chloromethane)을 0.3부량 첨가하여 80℃에서 40분간 반응시켜 중합도 1250의 수용성아크릴 수지를 중합하였다. 이때 그 반응식은 다음과 같다Add 99 parts of ammonium persulfate as a polymerization initiator to 99 parts of 25% acrylic acid monomer, add 0.3 parts of triphenyl chloromethane as a polymerization inhibitor, and react for 40 minutes at 80 ° C to polymerize a water-soluble acrylic resin having a degree of polymerization of 1250. It was. The reaction formula is as follows.

CH2=CH-COOH→(-CH2-CH-COOH-n CH 2 = CH-COOH-(-CH 2 -CH-COOH- n

친수성 전사잉크용 수지를 합성하기 위한 위의 공정에서 첨가하는 중합개시제인 과황산암모늄은 0.5-1.5부량 정도가 적당하며 또한 중합억제제인 트리페닐 크로로메탄은 소량 즉, 0.1∼0.3부량 첨가하는 것이 바람직하다.Ammonium persulfate, which is a polymerization initiator added in the above process for synthesizing the resin for hydrophilic transfer ink, is suitably about 0.5-1.5 parts, and a small amount of triphenyl chloromethane, which is a polymerization inhibitor, is added in an amount of 0.1-0.3 parts desirable.

[제 2 공정]Second Process

제1공정에 의해 제조된 수용성 아크릴 수지는 그 인쇄적성을 향상시키기 위하여, 수용성 아크릴 수지 50%, 에틸알콜 30%, 에틸렌그리콜 15%, 소포제 5%를 혼합하여 인쇄용 바니쉬를 제조하였다. 이 바니쉬에 염료 또는 기능성 색소를 첨가하여 친수성 전사잉크를 제조한다.In order to improve the printability of the water-soluble acrylic resin prepared by the first step, 50% water-soluble acrylic resin, 30% ethyl alcohol, 15% ethylene glycol, 5% antifoaming agent was mixed to prepare a varnish for printing. A dye or functional dye is added to the varnish to prepare a hydrophilic transfer ink.

[제 3 공정][Third process]

보호필름으로 투명 합성수지 필름을 선택하고 그 이면에 열융착형 접착제(EVA)를 도포하여 건조한 후 접착제층상에 제 2공정에 의해 제조된 전사잉크를 사용하여 그라비아 인쇄하므로서 잉크전사형 보호필름,즉 본 발명의 위조방지용 보호필름을 제조하였다. 보호필름의 베이스시트인 합성수지필름으로서는 투명PVC필름외에 PET필름 등을 사용할 수 있음은 물론이다.Select a transparent synthetic resin film as a protective film, apply a heat-sealing adhesive (EVA) on the back and dry it, and then gravure printing using a transfer ink prepared by the second process on the adhesive layer, that is, an ink transfer protective film, that is, the present invention The anti-counterfeiting protective film was prepared. As the synthetic resin film that is the base sheet of the protective film, PET film or the like can be used in addition to the transparent PVC film.

[제 4 공정][4th process]

제3공정에 의해 제조된 위조방지용 보호필름은 신분층이나 보안문서 표면과 상기 보호필름의 전사잉크층이 접하여지도록 열융착(라미네이팅)한다.The anti-counterfeiting protective film produced by the third process is thermally fused (laminated) so that the surface of the identity layer or the security document and the transfer ink layer of the protective film are in contact with each other.

이와 같이 신분증 등에 본 발명의 위조방지용 보호필름을 부착한 경우 신분증에 부착된 사진을 다른 사진으로 바꾸고자 보호필름을 분리하면 친수성인 전사잉크는 친유성인 접착제층과 분리되고 친수성인 사진표면의 젤라틴층과 결합되어 사진에 전사되므로서 위조나 변조된 사진은 사진위에 전사잉크층이 표현되지 아니하여 위조나 변조사실의 육안식별이 가능하게 된다.As described above, when the anti-counterfeiting protective film of the present invention is attached to an identification card or the like, when the protective film is separated to change the photo attached to the identification card, the hydrophilic transfer ink is separated from the lipophilic adhesive layer and the gelatin of the photo surface is hydrophilic. Forgery or altered photographs, combined with layers, are transferred to photographs, so that the transfer ink layer is not represented on the photographs, so that visual identification of forgery or modulation is possible.

따라서 본 발명은 보호필름의 접착제층에 이형제층을 형성시키지 아니하고서도 보호필름의 접착제층에 인쇄한 전사잉크층을 사진에 전사하므로서 사진의 교체를 불가능하게 하는 효과가 있다.Therefore, the present invention has the effect of making it impossible to replace the photo by transferring the transfer ink layer printed on the adhesive layer of the protective film to the photo without forming a release agent layer on the adhesive layer of the protective film.
